Hmmm, should I or should I not?!

I'm thinking of signing up for the ummm supernatural hardcore big bang ... I do have a story, well half done, but apparently mini bang only requires 5k of words or more (with me and my inability to shut up, I don't think word count would be a problem, LOL) and I could finish the story by the time drafts are supposed to be turned in ... and the story is kinda hardcor-ish and 'm kinda too shy/scared/embarrassed to post it just like that out of the blue, LOL, but if it would be a part of a challenge, then maybe .... pffff, God, idk ... AND then who would make art for that story!? I mean ''kink'' wise, because the ''kink'' the story has, it's not exactly everyone's cup of tea ... man ... *whines* this is what I call "hard decision making" :)
